Abstract

An ablation system comprising an atherectomy device and an aspiration catheter, each routed to a position just proximal to a lesion within a patient's vessel to ablate the lesion. The atherectomy device includes a flexible driveshaft coupled to an ablation burr.The ablation burr includes a concave front surface and a generally frusto-conical rear surface, both having an abrasive disposed thereon. The aspiration catheter has an elongate body and includes a centrally located lumen. The distal portion of the lumen is frusto-conical in shape and is positioned at the distal end of the catheter to define an aspiration mouth. The taper of the frusto-conical portion of the lumen corresponds to the taper of the rear surface of the ablation burr so that the ablation burr may be pulled back into the distal portion of the lumen of the catheter during operation of the system to clear captured ablated material therein.
